Honestly the lead up to BOTW's release wasn't exactly "hype" for me, so much as nearly 3 years of excruciating frustration. They way they kept us in the dark for 18 months, skipped E3 2015, refused to give us a release date until the 11th hour, truly Nintendo at its most fucking annoying. Thank fuck the game turned out so great, as I don't think any game has pissed me off more in the lead up to release, though Bayonetta 3 and Metroid Prime 4 will probably dethrone it for this dubious honour soon.
That's something you are doing to yourself because you create a strict priority order in your mind.
"This is a game that has my full attention despite not releasing anytime soon."
Of course that's going to be a taxing experience because you are constantly waiting for something that won't occur anytime soon. The absence of news is predictable, but you keep clinging to unrealistic expectations and hopes.
Play more Picross. That keeps your mind healthy.
